REED FOR AUTOMOBILE-HORNS.

Application led July 30, 1910. Serial No. 574,675.

Specification of Letters Patent.

Patented June 6, 1911.

To all 'whom Zt may concern:

Be it known that I, FRANK BIsHor, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented cert-ain new and useful Improvements in Reeds for Automo` bile-Horns, of which the followingcis a full, clear, and exact description, referencey being had to the accompanying drawings, forming part of this specification.

My invention relates to a reed for an automobile horn, and it has for its object the production of a reed of this descrip tion so constructed as to yeliminate liability of impairment of the reed by handling it, and further, to produce a reed in the use of which a more prolonged sound may be obtained than, is possible in the use of reeds now commonly in use.

The horn reed now most commonly in use comprises a reed body and a vibratory tongue at one side of the reed body adapted to vibrate to `and from said side. This tongue is exposed, and therefore, when the reed is handled, the tongue is liable to become bent or distorted so that it will'not perform its proper function, such bending or distortion being the most commonly due to the application of pliers 4to the reed for .the purpose of removing it fromits usual seat in the horn when it is necessary to clean the reed. By my improvement, I so protect the vibratory tongue that pliers may be used upon the reed without liability of the tongue being injured or displaced. The protecting means also serves to limit the degree of vibration of the vibratory tongue with the result of preventing undue rapid escape of air from the bulb used with the horn to which the reed is applied.

Figure I is a side elevation of my reed. Fig. II is an elevation of the rear end of the reed. Fig. III is a longitudinal section taken through the reed. Fig. IV is a cross section takenon line IV-IV, Fig. I. Fig. V is a perspective view of the vibratory tongue and its shank.

In the accompanying drawings: 1 designates the body of my reed having a shank 2. This body is of segment shape in cross section, and is closed at its front end by a curved end wall la.

3 designates a vibratory tongue opposing the open side of the reed body, and adapted to vibrate to and from said body. This tongue is fiat in shape where it opposes the mentioned parts.

by a shank 4, of segment shape in cross sec' tion. The arch pf the tongue shank extends Vin a direction` away from the open side of the shank of the reed body, as seen most clearly in Figs. II and III, thereby providing for the free passage of air through the rear end of the reed after it has entered the reed body between the vibratory tongue and theopen side of said body.

5 designates a guard, of segment shape'in cross section. This guard corresponds in shape substantially to the shape of the reed body 1, and it is located parallel with said reed body so that its open side faces the side of the vibratory tongue 3, opposite that that is faced by the reed body. The guard 5 is provided with a shank 6 which opposes the shank i of the vibratory tongue. The Shanks of the reed body and the guard 5 are held assembled by a clamping ring 7, which encircles them, and which, by holding the reed body and the guard in assemblage,

also serves to hold the shank ofthe vibra-V tory tongue between the Shanks of the first It is well to here note that as an additional means of securing said parts to each other, solder is preferably applied to the joints of the shanks and the clamping ring after the parts have been assembled.`

It will be noted now on referring to Figs. III and V, that the shank ofthe vibratory tongue 3 is provided with an outwardly jutting transverse bead 4a, and also on referring to Fig. III, that the shank of the guard 5 is provided with an internal trans verse groove 6a in which the bead @is seated.

4This construction provides for the vibratory tongue 3 being firmly held against longitudinal displacement in the reed, so that it will always be in proper position to perform its oiiice.

It will be plainly apparent that the guard 5 of my reed serves in conjunction with the reed body l to so house the sides of the vibratory tongue of the reed as to permit handling of the reed in any usual manner, including the application of implements to the reed for the purpose of removing it from the horn, and without any liability of said tongue being injured by such handling. It will be further apparent that, due to the presence of the guard 5, the vibrations of the vibratory tongue are limited in degree, and consequently, there is only suficient v bratory action to provide for the production of a sound desired to be produced by the of air, I make it possible to produce much i longer sound than would be produced in the use of reeds that permit the unnecessary passage of air therethrough.

I claim:

l. A reed comprising a body of segment shape in cross section', a vibratory tongue facing the open Side of said body, and a guard facing said tongue.

2. A reed comprising a body of segment shape in cross section, a guard facing the open side of said body, and a vibratory tongue between said body and guard, the body and guard having Shanks heldv in assemblage with each other.

3. A reed comprising a body of segment shape yin cross section, a guard facing the open side of said body, a vibratory tongue between said body and guard, the body and guard having Shanks held in assemblage with each other, and said tongue having a shank confined between the Shanks of the body and guard.

4. A reed comprising a body, a guard facing said body, and a vibratory tongue between said body and guard, the body and guard having segment shaped Shanks facing each other, and said tongue having a Segment shaped shank tting in the shank of the guard.

5. A reed comprising a body, a guard facing said body, and a vibratory tongue between said body and guard, the body and guard having segment shaped shanks facingA each other, and said tongue having a segment shaped shank fitting in the shank of the guard, said last named Shanks being provided with means for preventing longitudinal movement of said tongue relative to said guard.

6. A reed comprising a body, a guard facing said body, and a vibratory tongue between said body and guard, the body and guard having segment Shaped Shanks facing each other, and said tongue having a segment shaped shank tting in the shank of the guard, said last named Shanks having transverse bead and groove engagement with each other, substantially as and for the purpose specified.
